Abstract
The invention relates to a process of special high-performance acrylic polyurethane finishing varnish for a bus. The special high-performance acrylic polyurethane finishing varnish comprises components in groups A and B, wherein the group A comprises the following components in percentage by mass: 60-70% of acrylic resin, 8-12% of polyester resin, 0.1-0.3% of thixotropic agent, 0.4-0.8% of levelling agent, 1.0-1.5% of ultraviolet light absorbers, 1.0-3.0% of DBE slow drying agent, and 10.0-20.0% of mixed solvent; and the group B comprises the following components in percentage by mass: 80-90% of curing agent N3390 and 10-20% of mixed solvent. By adoption of the process of special high-performance acrylic polyurethane finishing varnish for a bus, the fullness, scratch resistance, levelling property and constructability of finishing varnish can be improved further.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of bus dedicated high performance acroleic acid polyurethane coating varnish technology.
Background technology
Improving constantly of Along with people's levels of substance, coating varnish have obtained increasing application on common Bus Carriage, to improve the exterior decorative effect and weather-proof, the medium corrosion resistance ability of Bus Carriage.General common coating varnish is to be base-material with the Hydroxylated acrylic resin, is equipped with a kind of high-grade paint that raw materials such as auxiliary agent, solvent make.If be used on the Bus Carriage, its decorative appearance performance, scratch resistance performance and workability also are with further raising, and the fullness ratio, scratch resistance performance, leveling characteristics and the workability that nowadays how to improve coating varnish have become a problem demanding prompt solution.
Summary of the invention
The objective of the invention is to effectively overcome the defective of prior art, a kind of bus dedicated high performance acroleic acid polyurethane coating varnish technology with high fullness ratio, scratch resistance performance, leveling characteristics and workability is provided.
Technical scheme provided by the invention is following: a kind of bus dedicated high performance acroleic acid polyurethane coating varnish technology, it comprises solidifying agent N3390, the mixed solvent of vinyl resin, vibrin, thixotropic agent, flow agent, ultraviolet absorbers, DBE drying retardant, mixed solvent and the second group of first group.
The quality proportioning:
First group vinyl resin 60-70% vibrin 8-12%
Thixotropic agent 0.1-0.3% flow agent 0.4-0.8%
Ultraviolet absorbers 01.0-1.5% DBE drying retardant 1.0-3.0%
Mixed solvent 10.0-20.0% skimmer 0.5%-1.5%
Colored paint 0.5%-3.8% solidifying agent 0.9%-3.8%
Second group solidifying agent N3390 80-90% mixed solvent 10-20%
More excellent is that described vinyl resin is made up of vinyl resin A, vinyl resin B.
A kind of method of manufacture that is used to produce described bus dedicated high performance acroleic acid polyurethane coating varnish technology, this method comprises the steps:
(1) drives resin, auxiliary agent and mixed solvent by prescription two, be uniformly dispersed.
(2) in the paint vehicle of processing, add other residue auxiliary agent and an amount of mixing solutions, adjust annual 80-100 and (be coated with 4 second
#Cup), filter discharging.
(3) the paint vehicle component that makes and curing agent component are mixed with coating varnish by 3: 1 proportion.
More excellent is the hardness that the Lacquer finish that makes is clear>=0.5, sticking power≤1, snappiness≤2mm, shock resistance>=50.
The advantage of bus dedicated high performance acroleic acid polyurethane coating varnish technology of the present invention: flow agent through with a kind of controllable incompatible surface tension that reduces coating system of coating system; Impel the paint film levelling; Eliminate the surface imperfection of paint film, thereby can further improve fullness ratio, scratch resistance performance, leveling characteristics and the workability of coating varnish.
Embodiment
Below be most preferred embodiment of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one; A kind of bus dedicated high performance acroleic acid polyurethane coating varnish technology, it comprises solidifying agent N3390, the mixed solvent of vinyl resin, vibrin, thixotropic agent, flow agent, ultraviolet absorbers, DBE drying retardant, mixed solvent and the second group of first group.
The quality proportioning:
First group vinyl resin 60-70% vibrin 8-12%
Thixotropic agent 0.1-0.3% flow agent 0.4-0.8%
